Thread: Help with a homework problem

I am doing an assignment that is asking for the user to put in the radius of a circle and the program figures out the area, diameter and circumference. It is using 2 different java programs to accomplish this. One with the info on how to get area, diameter and circumference and one is the demo that runs the program. I keep getting errors on my demo.

//  Circle Class
 
public class Circle
{
  private double rad;
  private double Pie;
  private double area;
  private double diameter;
  private double circumference;  
 
 
  public Circle(double Radius, double PI, double Area, double Diameter, double Circumference)
  {
    Radius = rad;
    PI = Pie;
    Pie =3.14159;
    Area = area;
    Diameter = diameter;
    Circumference = circumference;
 
  }

That is the first part and the second is:

import java.util.Scanner;
 
//  Circle Demo
 
public class CircleDemo
{
  public static void main(String [] args)
  {
 
  System.out.println("Rich Simmerman  3/4/2014/n/n");
 
  double circleRadius;
 
 
 
    Scanner keyboard = new Scanner(System.in);
 
 
  System.out.println("Enter the radius of the circle: ");
  circleRadius = keyboard.nextDouble();
 
[I] Circle data = new Circle(circleRadius);[/I]
 
  System.out.println("The circle's area is " + data.getArea());
 
  System.out.println("The circle's diameter is " + data.getDiameter());
 
  System.out.println("The circle's circumference is " + data.getCircumference());
 
 
  }
}

I am really just starting out and not sure what I'm doing.

--- Update ---

Sorry I didn't copy the whole first part of the program

//  Circle Class
 
public class Circle
{
  private double rad;
  private double Pie;
  private double area;
  private double diameter;
  private double circumference;  
 
 
  public Circle(double Radius, double PI, double Area, double Diameter, double Circumference)
  {
    Radius = rad;
    PI = Pie;
    Pie =3.14159;
    Area = area;
    Diameter = diameter;
    Circumference = circumference;
 
  }
 
 
 
 
  public void setRad(double Radius)
  {
    rad = Radius;
  }
 
 
 
  public double getRad()
  {
    return rad;
  }
 
  public double getArea()
  {
    return Pie * rad * rad;
  }
 
  public double getDiameter()
  {
    return rad * 2;
  }
 
  public double getCircumference()
  {
    return 2 * Pie * rad;
  }
}

That's why I'm asking, I 'm still new to this and just starting out. Most still doesn't make sense to me yet. This is only my 3rd assignment, most of the others have been pretty simple.

Ok, thanks!
